Abstract

Il est décrit un procédé de codage prédictif dimages, dans lequel de multiples ensembles de données de mouvement sont stockés dans des moyens denregistrement de données de mouvement, et une ou plusieurs paires comprenant deux desdits ensembles de données de mouvement qui comportent des valeurs différentes déléments structuraux est/sont calculée(s). Chacun des ensembles de données comprend deux éléments de données de mouvement dont les valeurs de nimporte quel élément constitutif varient. Un signal prévu dune région cible dune image est généré par compensation du mouvement au moyen deux éléments de données de mouvement provenant dun ensemble de données de mouvement choisi à partir dun ou de plusieurs ensembles de données de mouvement. Les deux ensembles de données de mouvement de ladite paire sélectionnée sont stockés dans les moyens denregistrement de données de mouvement en vue de la production de signaux prédictifs dautres régions.
